classes to configure servers

You can create custom
Java classes that extend server features or that perform some task when
a server instance starts or shuts down. These startup classes or
shutdown classes are loaded by the system class loader and therefore are
available to all resources on a server instance even if the resources
are managed by different containers. For example, EJBs and JMX clients
can access startup or shutdown classes even though their containers use
their own, higher level class loaders.

Because these are system-level classes, you must place them on the
server's classpath. If want to make custom classes available to multiple
applications but do not need the classes to be available at the system
level, consider deploying them as application startup classes.
